The probabilistic risk of any individual being a threat, regardless of characteristics, is so close to zero that trying to compare the risks, even to say "just about the same" is completely meaningless. But it's also silly to deny that orders of magnitude more "scary" "foreign" (pick a country) "men" have attempted to attack aircraft than Chilean toddlers. Both numbers are so low that any system at all is going to be overwhelmed by false positives.
